This invention relates to a textile spindle such asis commonly employed on twisters.

The primary object of the invention is to improve the running qualities of the spindle and reduce wear to a minimum. Y

--Among its features my invention embodies a spindle case having heat radiating fins and a whirl on the spindle and encircling the heat radiating fins of the spindle case so that as the whirl is driven to rotate the spindles draft of air will be created over the heat radiating fins to. cool the spindle case and spindle.

Other features include a single ball thrust 6 Claims. (01. 57-135) hearing against which the bottom end of the.-

spindle runs.

Referring to the drawings:

Figure 1 is a side view of a textile spindle embodying the features of this invention,

Figure 2- is a top plan view of the spindle illustrated in Figure 1,

Figure 3 is a bottom plan view of the spindle,

Figure 4 is a vertical sectional view showin certain portions in elevation to more clearly illustrate the details oi construction, 7

Figure 5 is a vertical sectional view through the spindle,

Figure 6 is a transverse sectional view taken substantially on the line 8-6 of Figure 5, and

Figure 7- is a transverse sectional view taken substantially on the line 'l-,'| of Figure 5.

Referring to the drawings in detail, a spindle case designated generally Ill comprises a shank l I having a screw threaded end l2 for the reception of a nut l3 by means oi which the spindle case is clampedto a spindle rail against a flange H formed on the spindle case body intermediate its ends. That portion oi. the spinis provided with annular heat radiating fins l8. Opening through the upper end of the spindle case is a bore I! which is provided adjacent its upper end with an enlarged bore l8 forming the upper bearing in the spindle case in which the spindle, to be more fully hereinafter described, runs. The lower end of the bore I'I communicates with a tapered bore extending i almost to the bottom end of the spindle case and seated at the extreme lower end of the bore 28 I .is a bearing ball 2|.

try into the conical bore 28 previously described. I

The lower end of the conical extension 24 rests dle case body 15 which projects above the flange 2 8 upon the ball'2i to provide for downward thrust ot the spindle blade 23 aswill be readily under-,

stood upon reference to Figure 5. Carried by the spindle blade 23 immediately above the upper end of the extension I! of the case 18 is a whirl designated generally 25 which comprises a cylindrical body 28 carrying at its lower end an outwardly extending annular flange 21 and at its upper end a hub 28 which is attached to the spindle blade by a drive fit so that when the whirl is rotated the spindle blade will be rotated in unison therewith. As shown the upper end oi. the hub 28 isi'ormed with a pad or seat 28 the upper surface oi which rises abovethe general level 0! the hub 28 so that when a bobbin is mounted on the upper end of the whirl it will be held in spaced relation to the hub. Formed at the junction of the side walls 28 of the whirl and the hub 28 are upwardly and outwardly extending passages 30 the purpose of which will more full hereinafter appear. The lower. end of the whirl is spaced from the upper surface of the flange H as will be readily appreciated upon reference to the drawings.

In operation it will be understood that as the whirl 25 is rotated the spindle blade 23 will rotate in unison therewith and due to the rapid motion of the passages 38 a draft of air will be. drawn upwardly between the heat radiating fins These openings are to provide ventilation sothat as the air is drawn upwardly by the rapid rotation of the openings in the whirl 25 it will enter the passages 82 at the bottom oi the sleeve 8i and pass upwardly over the fins I6 and then outwardly through the passages 82 at the top of the sleeve to be discharged through the openings 38 in the whirl. As previously stated such a.

sleeve Or thimble is not essential to the operation of the device but it does serve to improve-the appearanee of thecase H when the spindle and whirl have been removed therefrom.

While in the foregoing there has been shown and described the preferred embodiment oi this invention it is to be understood that minor 3 changes in the details 01' construction, combination and arrangement oi parts may be resorted to without departing from the spirit and scope of the invention as claimed. 3 I

What I claim is:

1. Ina textile spindle, a spindle case adapted to be mounted on a spindle rail, a spindle mounted in the case to rotate about a vertical axis, and a whirl on the spindle, said whirl surrounding the spindle case and having an annular row oi outwardly inclined openings in its upper end to create a draft of air upwardly between the spindle case and the whirl as the whirl rotates the spindle.

2. In a textile spindle a spindle case adapted to be mounted on a spindle rail, heat radiating fins on the spindle case, a sleeve encircling the of air through the sleeve and over the fins to cool the spindle case.

to be mounted on a spindle rail. heat radiating nns on the spindle case, a spindle mounted in the case to rotate about a vertical axis. a sleeve encircling the heat radiating tins and means operable upon rotation of the spindle to create a draft of air through the sleeve and over the fins to cool the case.

5. In a textile spindle a spindle case adapted to be mounted on a spindle rail, heat radiating Line on the spindle case, a spindle mounted in the case to rotate about a vertical axis, a whirl on the spindle and enclosing the heat radiating line, said whirl having spaced openings in its upper end which serve to create a draft oi! air over the line to cool the case. i

6. In a textile spindle a spindle case adapted to be mounted on a spindle rail, heat radiating heat radiating fins and means to create a draft fins on the spindle case, a thrust ball in the spindle case, a spindle resting on the ball and rotatable in the case about a vertical axis, a spindle blade at the upper end of the spindle, a whirl on the spindle, said whirl encircling the heat radiating fins and having an annular row of spaced openings at the junction of its top and side walls whereby when the whirl is driven a draft of air will be created over the fins to cool the case.
